We describe radio surveys covering the sky from -87.5 deg to + 10 deg declination made using the Parkes 64 m radio telescope with the NRAO multibeam receiver at a frequency of 4850 MHz during 1990. We have fully reduced the data from the Southern Survey and Tropical Survey. Together, these surveys cover 4.51 sr and contain 36,640 sources to a flux limit that is, typically, about 35 mJy but varies as a function of declination. They increase the number of known sources in the regions surveyed by approximately a factor of five. In this paper, we describe the overall PMN Surveys, the data reduction techniques adopted, and assess the data quality of the two lists of sources resulting from the Southern and Tropical Surveys.
